DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for manufacturing a wave-breaking block for molding a large-sized block such as a wave-breaking solidification block.

[0002]

TECHNICAL FIELD The present invention relates to large blocks such as wave-breaking consolidation blocks which are located in and around sea areas, buildings and facilities near and inside a port to protect buildings and facilities around the port from storms and high waves. Is commonly used. For example, a wave-breaking solidification block called a shake block in which four pairs of legs are symmetrically protruded from the main body of a formwork is known. The formwork for forming the block is a triangular star-shaped bottom plate and a triangular star-shaped form. 3
Assembling the formwork while connecting the four sets of frame forms consisting of the set of peripheral side wall forms with bolts, and using the raw concrete from the upper end opening of the formwork.
After inserting the vibrating rod into the raw concrete after filling it in the pouring method, vibrating it,
The fresh concrete is tightened while jigging to increase the density of the concrete. In this conventional mold, the upper end of the upper end of the mold as a raw concrete input port is narrowed in accordance with the shape of the block itself. Bubbles are difficult to remove even when spased with a vibrating rod or flat plate, remain on the inner surface of the mold, and form avatar-shaped nests on the outer surface of the molded block, reducing the strength and service life of the block. In addition, there is a disadvantage that the aesthetic appearance is impaired due to the avatar-like marks on the surface. In order to solve this problem, the applicant has proposed a method of preventing the generation of air bubbles when molding a large block disclosed in Japanese Patent Publication No. 2-30842.

[0003]

FIGS. 9 and 10 show Japanese Patent Publication No.
No. -30842 shows a device configuration of a formwork, in which an adjustment cylinder 2 is vertically arranged so as to penetrate an inverted trapezoidal storage hopper 1.
And a frame-shaped compressor 3 for supporting the storage hopper
Is suspended at the upper end opening of the mold frame 4 and an inflow port 5 is provided at a vertical intermediate position of the adjusting cylinder, and the piston 6 is pushed downward while pushing the ready-mixed concrete put into the hopper 1 from the inflow port. Formwork 4
It performs the compacting action of the fresh concrete inside. However, in this form, the lowermost end of the piston 6 is the upper end of the form, which is the lower end of the adjusting cylinder 2, and therefore, as shown in FIG. Prevention of bubble generation on the inner side of the formwork in J is not perfect,
For this reason, air bubbles could not be removed, and cracks were generated from the portion where the air bubbles stayed. In addition, after casting of ready-mixed concrete, water rises on the concrete surface to cause bridging and latence, which lowers the strength and durability of the block. It has been difficult to completely prevent the problem of deteriorating aesthetic appearance due to the dripping-like breathing. Further, when the piston is pushed down, the ready-mixed concrete flows backward from the inflow port 5 and is pushed back to the hopper 1 side, so that the worker performs the operation of pushing the ready-mixed concrete again from the inflow port 5 while performing the pressing operation of the piston a plurality of times. Therefore, it takes a long time to perform a block forming operation for each block, and when a large number of blocks are formed in a harbor or the like, there is a disadvantage that the entire work is significantly prolonged and the working efficiency is deteriorated.
Furthermore, in this formwork apparatus, the work must be performed at a position close to the piston pressing work while the worker is mounted on the frame body of the compressor, which poses a problem in terms of ensuring labor safety. Was.

An object of the present invention is to provide an apparatus for manufacturing a wave-dissipating block capable of manufacturing a high-quality wave-dissipating block without causing cracks or pock in the block. Another object of the present invention is to provide an apparatus for manufacturing a block for wave-dissipation and the like, which can surely perform a compacting action even in a place where it is difficult to sufficiently fill concrete. Another object of the present invention is to sufficiently remove moisture in the poured ready-mixed concrete to prevent occurrence of breathing and pocking, to improve the appearance of the product concrete block, and to maintain high quality. An object of the present invention is to provide an apparatus for manufacturing a block for wave extinction. Further, another object of the present invention is to eliminate the necessity for an operator to deploy the ready-mixed concrete at a position close to the ready-mixed concrete work during compaction of the ready-mixed concrete, and to surely prevent occupational accidents and the like. An object of the present invention is to provide an apparatus for manufacturing a block for corrugation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is an explanatory view of the entire front configuration of a manufacturing apparatus (hereinafter referred to as “manufacturing apparatus”) 10 for a wave-eliminating block according to an embodiment of the present invention. Hollow outer cylinder 14 vertically inserted and arranged in three-dimensional formwork
And a pusher 16 slidably provided vertically slidably in the hollow outer cylinder, and a drive unit 18 for driving the pusher.

In FIGS. 1, 4 and 7, the three-dimensional form 12
Is a shake block type which is formed in a tetrapot shape by assembling a metal plate material with bolts or the like so as to have a main body portion 20 and a substantially cylindrical short body-shaped leg portion 22 extending in four directions radially symmetrically from the main body portion 20. It consists of a hollow three-dimensional formwork. The interior of the three-dimensional form is closed by a metal plate material, and only the upper end of a vertical leg 22a that rises vertically upward from the main body 20 with three legs 22 landing is opened. Is the inlet 24 for the ready-mixed concrete N. In the embodiment, the charging port 24 is formed in a circular shape. In FIG. 5, a flat receiving portion 26 having a bolt hole (not shown) enlarged in a flange shape in the radial direction from the upper end portion of the vertical leg portion 22a.
Is provided.

In the figure, the hollow outer cylinder 14 is inserted and fixed into the inlet 24 from above the vertical leg portion 22a, and the lower end of the hollow outer cylinder 14 is projected into the three-dimensional formwork 12. The hollow outer cylinder 14 is formed of a hollow metal cylinder having upper and lower ends opened,
It is inserted vertically from the slot 24. At the position near the upper end of the hollow outer cylinder, a flange portion 28 that is enlarged from the outer periphery in the direction orthogonal to the longitudinal direction of the outer cylinder is fixed, and when the hollow outer cylinder 14 is inserted from the input port 24 and lowered, This brim part 2
8 comes into contact with the receiving portion 26 of the vertical leg portion 22a, and the clamp member 2
7 are connected and fixed by bolts or the like. As a result, as shown in FIG. 5, the hollow outer cylinder 14 is vertically arranged and fixed in the three-dimensional form with most of the hollow outer cylinder in the longitudinal direction protruding or embedded in the three-dimensional form 12. You. Then, by pushing down the pushing body 16 having the pushing portion 30 for compressing the inside of the hollow outer cylinder 14 through the driving portion 18, a large compaction action is produced for the ready-mixed concrete put into the formwork 12, and It is possible to produce a high-quality wave-dissipating block without causing cracks or pock in the concrete block. In addition, the compressive force of the pressing body against the ready-mixed concrete is high, so compaction is performed a plurality of times, that is, it is not necessary to repeatedly perform the pressing operation of the pressing member, and the compacting operation by one pressing is sufficient. Time is greatly reduced.

In this embodiment, as shown in FIG. 2, a large number of inner and outer communication holes 32 are provided in the cylindrical wall 14a of the hollow outer cylinder 14. As will be described later, the inner and outer communication holes 32 compact the fresh concrete when the pusher 16 is pressed, and at the same time, the fresh concrete is contained in the gap between the hollow outer tube 14 and the pusher 16 through the inner and outer communication holes 32. The water content is removed by injecting water.

In FIG. 2, three notches 34 are formed at the lower end of the hollow outer cylinder 14 at regular intervals in the circumferential direction so as to be concave upward. The notch 34 is used for the three-dimensional form 12
Are set at circumferential positions corresponding to the directions of the three legs 22 in the landing state, and when the ready-mixed concrete is discharged from the hollow outer cylinder 14 into the hollow mold 12 by the pressing and compressing operation of the pressing portion 30. By discharging the ready-mixed concrete to the outside earlier than the circumferential portion other than the notch portion 34, the concrete density at the connection portion J (the surface side of the main body portion 20, that is, the inner surface side of the formwork) between the legs is increased. The generation of air bubbles is surely prevented. Notch 34 in the embodiment
Is recessed upward, that is, formed by notching in an inverted U-shape, but the shape of the notch is not limited to this, and is a saw blade shape, a corrugated shape, other shapes and continuous or discontinuous, They may be arranged at equal intervals or unequal intervals. The number may be one or two or more. In the figure, reference numeral 36 denotes a metal fitting for reinforcing the flange portion 28.

In FIGS. 1, 6, and 7, a pusher 16 is provided inside the hollow outer cylinder 14 so as to be vertically slidable in the hollow outer cylinder. The pressing body 16 includes a pressing portion 30 that compresses the inside of the hollow outer cylinder at the time of pressing down the inside of the hollow outer cylinder.
In the embodiment, the pushing body 16 is formed of a metal hollow cylindrical body, and includes a pressing portion 30 as a circular flat piston at the lower end of the cylindrical portion 40. As shown, the cylindrical portion 4
The diameter of the pressing portion 30 is set to be larger than the diameter of 0. As shown in FIG. 6, the size of the circular flat plate of the pressing portion 30 is set so that it can slide almost in close contact with the inner diameter of the hollow outer cylinder 14, and the inner wall of the cylindrical portion 40 and the hollow outer cylinder 14. Is formed between them. Thus, when the pusher 16 presses down the inside of the hollow outer cylinder 14, the green concrete is compacted while applying a compressive force to the inside of the hollow outer cylinder by the pressing portion 30. And this pusher 1
6 descends to perform the compressing operation in the hollow outer cylinder 14, squeezes out the water contained in the ready-mixed concrete while compressing the fresh concrete, and removes the water from the inner and outer communication holes 32 of the hollow outer cylinder 14. The liquid is injected into the gap S in the outer cylinder 14 and flows. The inflowing water stays in the hollow outer cylinder 14 when the pushing body 16 is pulled out of the hollow outer cylinder 14, and is directly discharged to the outside by, for example, a manual pump or a pumping container (not shown).

In FIG. 3, a pushing body 1 made of a hollow cylindrical body is used.
The upper end side of 6 is connected to a stopper 42 in the form of a donut disk whose diameter is enlarged from the cylindrical portion 40. The total length of the hollow cylindrical body as the pushing body is set to be substantially the same as the length of the hollow outer cylinder 14, and the pushing body 16 is inserted into the hollow outer cylinder 14 from above, and the lowering is stopped by the stopper portion 42. In this position, the lower end of the pusher 16 substantially coincides with the lower end of the hollow outer cylinder 14. Also, three locking fittings 44 project upward from the stopper portion 42. And
This locking metal fitting has a locking hole 4 for a cable of a driving section described later.
6 are perforated.

1, 4, 5, and 6, a driving unit 1 that drives a pushing body 16 in a compression direction in a hollow outer cylinder 14.
8 are provided. The drive unit 18 drives the pusher 16 so as to be slidable so as to be able to advance and retreat vertically in the hollow outer cylinder 14. For example, using a backhoe or other working machine, the upper end of the pusher 16 is attached to the tip of the arm. May be fixed and driven downward from above. Further, a vibrator may be provided at the arm tip side of the working machine as appropriate, and the inside of the hollow outer cylinder 14 may be driven in the compression direction while vibrating the pusher 16, thereby driving into the three-dimensional form. The compacted work of the ready-mixed concrete can be performed efficiently.

In the embodiment, the driving section 18 has a cable 48 whose one end is locked by the pusher 16 and the other end is locked by the lifting section 56 of the work machine, and the pusher is hollowed by the lifting operation of the lifting section 56. A conversion body 50 that moves in the compression direction within the outer cylinder 14. In FIGS. 1 and 6, pulleys serving as converters 50 are attached to the distal ends of the three legs 22 in a landed state having a hollow short body. On the other hand, one end of the cable 48 is locked via a hook member 52 in a locking hole 46 provided in a locking metal member 44 on the upper end side of the pushing body 16. The other end of the cable is a pulley (50)
And hooked on a lifting hook as a lifting portion 56 suspended from a working machine (not shown) via a hook member 54. As a result, by moving the working machine upward, each of the three ropes 48 is forced to move in the direction of compressing the inside of the hollow outer cylinder by the pushing body 16 via the pulley as the conversion body 50, and the three-dimensional cable 48 is moved three-dimensionally. The ready-mixed concrete poured into the formwork is compressed and compacted.

Next, the operation of the apparatus for manufacturing a wave-dissipating block according to an embodiment of the present invention will be described with reference to FIGS. 5 to 8. For example, a three-dimensional formwork 12 for a 5-ton concrete block will be described. 3D form 1
The ready-mixed concrete is poured from the input port 24 of the second vertical leg portion 22a. After filling the ready-mixed concrete to reach the height of the inlet, the hollow outer cylinder is inserted from the inlet while being suspended and supported by a working machine as shown in FIG. 7, and the lower end side is solidified as shown in FIG. The plunger is lowered into the mold so that it is almost entirely housed in the three-dimensional mold. Then, the collar 28 of the hollow outer cylinder 14 is brought into contact with the receiving portion 26 of the vertical leg 22a, and the hollow outer cylinder 14 is housed in the vertical leg 22a by the clamp member 27 as shown in FIG. Fix it.

Next, as shown in FIG. 8, the pusher 16 is suspended from a working machine or the like and inserted into the hollow outer cylinder 14 while being positioned. With the pusher inserted to some extent, as shown in FIG. 1, one end of the cable 48 is locked by a hook or the like in the lock hole 46 of the lock fitting 44 on the upper end side of the pusher 16, and the other end is connected. Each of the three pulleys (50) attached to the landing leg portion 22 hangs around the pulley (50), and the lifting hook (5
Lock in step 6). In this state, by lifting the lifting hook, the pushing body 16 is pushed down in the hollow outer cylinder 14 by the lifting force of the working machine via the cable 48 and the converter. At this time, as shown in FIG. 6, the piston body of the pressing portion 30 compresses the inside of the hollow outer cylinder 14 and compacts the poured fresh concrete, while squeezing out the water contained in the ready-mixed concrete to remove the hollow concrete. Cylinder 14
Pressure is injected into the gap S between the hollow outer cylinder 14 and the cylindrical portion of the pushing body 16 through the inner / outer communication hole 32 formed in the cylindrical wall of the cylinder. Then, the inflowing water stays in the gap S.

The pushing body 16 is pulled up and removed from the hollow outer cylinder 14, and the hollow outer cylinder is also separated from the three-dimensional form. After that, the water remaining inside the hollow outer cylinder is pumped out by a pump or a pumping container. Thereafter, ready-mixed concrete having a volume corresponding to the volume of the hollow outer cylinder is poured into the hollow portion opened in the trace of the hollow outer cylinder, and is cured and solidified. Unlike the case where the driving section is directly pressed down by fixing the upper end side of the pusher with the arm of the backhoe or the like, the cable 48 and the converter 5
0 and the lifting unit 56 attached to the arm of the work machine
The lifting element 16 compresses the inside of the hollow outer cylinder just by lifting the
The worker can always work in the area away from the compaction work position of the pusher without performing the work of pushing back the ready-mixed concrete by arranging it near the vertical leg portion 22a. The above safety is greatly improved, and the occurrence of occupational accidents can be reliably prevented.

The apparatus for manufacturing a wave-eliminating block according to the present invention is not limited to the configuration of the embodiment described above.
Arbitrary modifications may be made without departing from the essence of the invention described in the claims. For example, instead of the cylindrical body, the pushing body may be constituted by a pinstone rod having a pushing portion capable of compressing the inside of the hollow outer cylinder, a plunger body to be pushed down, or the like. Further, the present invention can be applied not only to the shake block type but also to the manufacture of other hollow concrete blocks such as a hollow triangular type, a tetrapot type, and any other closed type.
